<jats:title>Abstract</jats:title><jats:p>High‐molecular‐weight hyaluronan acts as a ligand of the tumor‐suppressive Hippo signal, whereas degradation of hyaluronan from a high‐molecular‐weight form to a low‐molecular‐weight forms by hyaluronidase 2 inhibits Hippo signal activation and thereby activates the pro‐oncogenic transcriptional coactivator yes‐associated protein (YAP), which creates a cancer‐predisposing microenvironment and drives neoplastic transformation of cells through both cell‐autonomous and non‐cell‐autonomous mechanisms. In fact, accumulation of low‐molecular‐weight hyaluronan in tissue stroma is observed in many types of cancers. Since inhibition of YAP activity suppresses tumor growth in vivo, pharmacological intervention of the Hippo‐YAP signal is an attractive approach for future drug development. In this review, pharmacological intervention of excessive hyaluronan degradation as a novel approach for inhibition of the Hippo‐YAP signal is also discussed. Development of hyaluronidase inhibitors may provide novel therapeutic strategies for human malignant tumors.</jats:p>
